Answer:
a part of mathmatics using diffrent terms to solve functuons
Roots test tells us to take the factors of the 20 divided by the factors of the coefficient of the the first.
factors of 20 are 1,2,4,5,10,20
factors of 1 are 1
so plus or minus 1/1, 2/1, 4/1, 5/1, 10/1, 20/1 are all possible rational zeros
A function is decreasing if, reading from left to right, we can see that the graph of the function goes down.
Here we can't see the graph, but we have a brief description.
"the graph goes up until it reaches a maximum at (0, 5), then the graph reaches a relative minimum at (1, 4), then it goes up again"
Now, the graph was going up until it reached the maximum, so at that point, the graph starts going down.
The graph will go downwards until it reaches the minimum, at that point the graph starts increasing again.
So the graph only goes down between x = 0 and x = 1.
we can conclude that the interval on which the given function is decreasing is [0, 1]

Answer:
Number of T-shirts sold = 80 and number of shorts sold = 20
Step-by-step explanation:
This question is incomplete. If we have to calculate the number of shirts and T-shirts sold by Dots then we will calculate this question as below.
Let the number of shorts sold = s
And the number of T-shirts sold = T
Dots sells T-shirts at $5 and shots at $8 in April.
Equation for this situation will be,
5T + 8s = 560 -----(1)
Number of T-shirts sold are 4 times the shorts,
T = 4s ----- (2)
By substituting the value of T from equation (2) in equation (1),
5(4s) + 8s = 560
20s + 8s = 560
28s = 560
s = 20
From equation (2),
T = 4(20)
T = 80
Number of T-shirts sold = 80 and number of shorts sold = 20
